To all whom it may concern",

Be it known that I, GUs'rAv SEGSCHNEI- DER, a citizen of the United States of America, residing at Yonkers, in the county of Westchesterand State of New York, have invented certain new and useful Improvements in Machines for Welting and Rounding Hat- Brims, of which the following isa specification.

This invention relates to an improved inachine for welting and rounding hat-brimsby which the manual labor in accomplishing the welting and rounding operation is dispensed with and the same accomplished mechanically in a quick and effective manner; and for this purpose the invention consists of a machine for welting and rounding hat-brims which comprises a table, a stationary ring on said table corresponding] to the shape of the hat-carrying templet, a welting ring, means for heating said ring when in raised position, means for lowering said ring and forming the welt over the circumference ofthe templet, and means for imparting a short vertical reciprocating motion to the welting ring.

The inventionconsists further'of certain details of construction and combinations of parts to be hereinafter described and claimed.

In the accompanyingdrawings, Figure represents a front-elevation of my improved machine for welting and rounding hat-brims, showing the welting ring in lowered position locked to the table, Fig. 2 is a detail vertical device, drawn on a'larger scale, and Fig; 6 is aplan-view of Fig. 5.

Similar letters of reference indicate corresponding parts throughout the figures.

Referring to the drawings, a/represents the supporting frame .of my. improved machine for welting and rounding hat-brirns. On the frame a is supported a tabled which is provided with an opening-of sufficient size,

for inserting difierent sizes of templets t, as required for the difierent sizes of hats: The

templets are made of an oval body ofwood for the crown and a corresponding plate of zinc for the brim, the parts being united in any suitable manner. On the table a is arranged a stationary ring I) which corresponds in generalshape to the templet, the base of the ring being attached to the table in any suitable manner. Into the ring I) is fitted a welting ring d, which is also made to correspond in shape to the shape of the templet t and ring b, and which is supported by means of ears (1 at diametrically opposite points to two vertically-guided rods d which are guided in openings of the table a and sleeves of on the frame a, and raised or lowered by means of a transverse treadle-rod 1" which is connected by bracket-rods r and cross-rod r to the lower ends of the vertically-guided rods d said treadle-rod, guide-rods and welting ring being counterbalanced by a weight (i which is connected by cords d passing over pulleys d at the under-side of the table with fixed sleeves d on the rods (1 as shown clearly in Figs. 1 and 3.

. At one corner of the table a is swiveled an upright arme, which is bent at right angles at its upper part and then bent in downward direction at its inner end, the downwardlybent end supporting a hub 6 provided with radial pi es- 6 having discharge-orifices at their en s- The hub e is connected by a suitable hose or ipe e with a supply of gas and air or other eating medium. The hose or pipe e is provided with a stopcock for turning on or cutting off the supply of gas to the radial pi es or arms. The heating jets emitted by tfie radial arms e serve for heating the welting ring (1, which latter is raised arm 6 is swung with theheating arms 0 ear of the table, as shown in dotted lines in Fig. 4,

:so astogive free access to the table and the hat supported in the templet placed in the opening of the same. At the upper ends of the vertically-reciprocating rods d are arranged, above the ears which connect them with the. welting ring, collars d, screw-nuts dand helical cushioning springs of, which latter are interposed between the ears and collars, so that a certain degree of yielding motion can be imparted to the welting ring, as required by the welting operation.

At the lower part of the frame a are arranged, below the cross-rod r connecting the lower ends of therods d rods f which extend to the rear of the frame and which are connected by a transverse pivot rod f at their rear ends, said rod 1 being connected by a connecting-rod f with an eccentric f on a shaft .9, which is supported in suitable bracketbearings at the upper rear-part of the frame a and which receives rotary motion by a beltand-pulley transmission from an overhead shaft, electric motor or other source of power. In the lowermost position of the treadle 1, W, W the cross-rod r rests on the oscillating lever and transmits thereby a quick reciprocating movement to the welting ring, said cross-rod being held against said levers by the pressure of the operators foot on the treadle rod 1. During this reciprocating motion of the welting ring, it yields sufficiently by its cushioning springs, so that an even pressure is exerted by the welting ring on the folded or bent-over edge of the hatbrim. The welting ring is preferably made of cast-iron, and provided at its lower edge with a face-plate d of brass, as shown in Fig. 5, the welting ring and its face-plate being thoroughly heated by the heating jets of the gas-arms, so as to exert by combined pressure and heat an effective welting action on the bent-over edge of the hat-brim. The welt is thereby retained in position when the hat is removed from the machine and templet. The welt can be bent over the circumference of the templet, either above or below the same, according as the welt is to be formed at the inside or outside of the brim, the hat shown in the drawing being a military hat, in which the welt is formed on the outside of the edge of the brim.

When the welt is sufiiciently worked upon by the welting ring so as to retain its position, the welting ring is locked in position on the table by means of pivoted clamps g, located at opposite points on the table, so that the welt is firmly pressed down on the templet. In this position the cutting off or rounding of the inner edge of the welt is accomplished along the lower edge of the welting ring by means of a cutting knife is, which is guided in an upright holder 761 and retained by a set screw W, the holder being provided with a handle 71. by which it is pressed with its rounded-off face against the inner edge of the wel ting ring. To the under-side of the holder is applied a tongue 7L1 which is attached to the under-side of the handle h, and which is pro vided with a shoulder b so as to permit the entry of the irregular edge of the welt be tween the handle and tongue, the tongue being rounded off at its edge so as to pass readily, in connection with the rounded-off face of the holder, around the inner surface of the welting ring and produce by the cutting action of the knife the even cutting off of the edge of the welt, as shown in Figs. 5 and 6. In place of the cutting device shown, any other equivalent cutting means may be employed.

WVhen the machine is used for welting and rounding off army hats, holes have to be punched into the brim near the base of the crown for applying the hat-cords. For this purpose the table a and the base of the stationary ring I) are provided at each side of the hat-crown with parallel slots 0, in which are placed two punches p, one ateach side of the crown. The punches p are supported on base-plates p which are attached to the table a by screws f that are passed through slots 0 of the base-plates p, as shown clearly in Figs. 5 and 6. The punches are adjustable relatively to the base of the crown and are provided with rounded-oil upper ends and placed in register with openings 0 in the templet at each side of the crown of the hat; so that by a few blows of a mallet the punches ass through the brim and cut clear, neat ioles, one at each side of the crown. \Vhen the brims of ordinary hats are welted and rounded off on the machine, the holes in the brim are not required, in which case the punches can be removed or retained in position without being used.

The operation of my improved machine for welting and rounding hat-brims is as follows: The hat is placed on the templet and then inserted into position in the oval opening at the center of the table with the crown in downward direction, the bent-over edge of the brim being folded over the outer circumference of the templet. The gas-arms are then moved by means of the swiveled arm over the table and the welting ring is placed in position around the same, as shown in dotted lines in Fig. 1 and in full lines in Fig. 3, so that it is thoroughly heated up by the gas-jets. The welting ring is then lowered by the treadle-rod r against the balanceweight, until its lower edge arrives on the bent-over welt of the hat-brim and presses the same firmly on the templet, as shown in Fig. 5. When the treadle-rod arrives in its lower position, the transverse rod of the guide-rods rests on the lever-rods f and imparts a quickly repeated reciprocating motion to the welting ring, so that the pressure of the ring on the moist welt gives the permanent shape to the welt, according as the same is folded over the outer circumference of the templet. hen the welt is formed by the combined action of the heat and pressure of the welting ring the latter is locked. in position on the table by turning over the clamping lugs, as shown in Figs. 1 and 2, so as to hold the welt in position on the templet. The cutting knife is then placed. in position against the inner surface of the welting ring and moved over the welt and templet, so to cut off the irregular edge of the welt, as shown in Figs. 5 and 6. During this operation the gas-heating arms are moved to the outside of the table by means of the swiveled supporting arm so as to clear the table and be not in the way. Simultaneously with this motion the gas-supply cock may be partly closed so that the size of the gas-jets is reduced. The holes are next punched in the brim by the blows of a mallet on the punches,

skilled hand-work heretofore required for producing these operations is dispensed with and the operations performed by the machine.

Having thus described .my invention, I claim as new and desire to secure by Letters Patent 1. In a machine for welting and rounding hat-brims, the combination, with a table having a templet-opening, and a templet, of a stationary oval ring on said table, a welting ring fitted within the same, means for raising and lowering said welting ring, a heating device for the welting ring, and means for swinging said heatingdevice over the table.
